.To all/whom z'tmay concern:

Be it known that I, Bonner I. Enwnnns, a

citizen of the United States of America, re-

siding" at'Detroit, in the county of Wayne and State of Michigan, have invented eer- .talIL new and useful Improvements" in Corner-Bead Clamps, of which the fol lowing lsa specification,"reference being 7 had therein tothe accompanyingdrawings.

The invention relates to corner bead clamps designed for the use of plasterers in the proper positioning and holding of said beads untilthe plaster is set. It is the object of the invention to provide-a temporary clampwhich may be quickly positioned and which will securely hold the bead properly aligned while the plaster is being laid and subsequent thereto until it is completely hardened. The clamp may then be removed and can be used again for other WOI'K. The invention therefore consists in the construction as hereinafter set forth.

In the drawings:

Figure 1 is aside elevation of a brick wall showing the corner bead secured thereto by my improved clamp;

Figure 2 is a horizontal section thereof;

Figure 3, is a perspective view of the clampy 1 i Figure at is a perspective view of one con- 1 struction of corner bead;

Figure 5 is a similar view of a modified construction of corner bead;

Figure 6 is a View similar to Figure 2, showing a modified construction of clamp.

In plaster finish where there is a projecting corner, 'it is necessary to reinforce the same to prevent breaking of the plaster. One method commonly used is the employment of a metallic head which extends along the angle of the wall and is embedded inthe plaster, so as to beconcealed thereby but to nevertheless reinforce the same. In placing these beads it is essential that they should be lined up with the finish surfaces, so as to neither project therebeyond or to be so deeply embedded as to fail in reinforcement. If, however, this beading is placed by the lather or by the carpenter, it is difiicultto properly align the same, for the exact plane of the finish surface may not be fully deter-- mined. With my improved construction the reinforcing bead may beplaced by the plasterer after therwork has progressed sufficiently to fully determine the planes of the intersecting surfaces. Also the construction is such that 1t can be quickly applied and when the work 18 completed, as quickly removed. r

Indetail, A-is a wall, such, for instance, as a'brickwall, which is to be plastered, and B isa projectingcorner. C is the corner bead for reinforcing the plaster at the corner. D is my improved clamp which comprises a 'pair of hinged j aw members D and D suitably fashioned at D and D for engaging thefibead. As shown in Figure :2, these members have shanks and E which extend at right angles to each other and which are preferably connected with e tension strips of wood F and F. One or more surfaces of the clamp, preferably the inner surface of the shanks E and E, and the extension members F and F thereof extend in the plane of the finished surface of the plaster when the head is properly positioned for embedding; therein. Therefore, in the setting of the clamp it is only necessary to secure the same to the wall by nails or otherwise with this surface properly positioned. The work may be facilitated by first plastering the wall, or a portion thereof,

adjacent to the corner and then sett ng; the

clamp so that the inner faces referred to will lie flushwith this plastered section. After the clamps are secured, the'work of plastering may be continued up to the corner cm bedding the bead and when the plaster has hardened, the clamps are removed.

With the construction shown in. Figure 6, instead of securing the clamp by members engaging the angling: surfaces of the wall, the clamp is secured by engagement with one of the surfaces, which permits of applying the bead to a corner but slightly projecting. \Vith this construction the co-operating jaw members G and G which clamp the head at G and G respectively are slidably engaged with each other and are including a securing shank extending from one of said jaws and having the inner surface thereof adapted to be positioned in alignment with the finish surface of the wall when the head is properly positioned at the corner thereof.

4. A bead clamp comprising a pair of clamping jaws for gripping the head, and including a securing shank extending from one of said jaws and having the inner surface thereof adapted to be positioned in alignment with the finish surface of the wall when the bead is properly positioned at the corner thereof.

5. A. bead clamp comprising means for the corner thereof.

gripping the bead and including a securing shank having the inner surface thereof adapted to be positioned in alignment with the finish surface of the wall when the head is properly positioned at the corner thereof, and means for temporarily securing said shank to the wall.

6. A head clamp comprising a pair of pivoted jaws for gripping the bead and shanks respectively eXtending from said jaws and having theinner surface of one of said shanks adapted to be positioned in alignment with the finished surface of the wall when the head is properly positioned at the corner thereof. v V 7 7. A bead clamp comprising a pair of pivoted jaws for gripping the bead and shanks respectively extending from said jaws, said shanks being disposedin planes at right angles to one another and having their inner surfaces adapted to be arranged in alignment with the finish surface of the wall when the head is properly positioned at Intestimony whereof Iafiix my signature.
